Usability Screen width limit

Just wondering if there's a limit to the viewable screen width? Reason being I have several Freelander sales brochures on ere with pic's side by side to give you the full open book 2 page view. Many of these now show the pic's one below the other, so I assume I've gone over the viewable width limit. Hence the pic's now display one below the other as opposed to side by side?

I have put pic's side by side like this in the freds.
[start]pic1[end][start]pic2[end]

Had a play with this before. My monitor is 23 inch. If I use the iexplore zoom level in the bottom RHS of the display to zoom out, the LZ window shrinks. The left and right side marker strips then move in, and the pic's stay in the same position. So I must have hit the limit on viewable width.

If necessary I will reduce the pic size. The reason for them being big is due to some of the words being too small to read. Most of the brochures are A4 when closed. The alternative would be to pdf them and add them to my dump truck free account for peeps to download instead of viewing on ere.

So the reason it is doing that is because the forum is now responsive, so changes the size of the pictures depending on screen size. The solution would actually be to retain the large size but merge the two images together as one, this way they will always show properly, and will adapt to the users screen size. Anything that is to small to read can be clicked on to get the full size to show.

Thanks. Pic's were cut in half due to size limits on photobucket, but I will look into other area's of storage and try fix it as you suggest.

I suggest you upload here now, it should accept and work with large images, let me know if you have any problems and I'll try to fix it.

thanks

the new layout will also help
